Espresso is usually a blend of Arabica and Robusta coffee beans which are dark roasted to give it a more intense flavour. The coffee grind are finer because of the brewing technique. In brewing on an Espresso machine, hot and high pressured water is forced through the compacted coffee powder. The resultant drink from the liquid dripped from the machine is an extraction of the coffee. The extraction process takes less than 25 seconds. A good Espresso machine maintains the water at the right temperature, and controls the pressure and the duration of the extraction. On the surface of an Espresso drink, you will see an oily layer of brownish light foam. This is known as the crema, derived from the natural oil of coffee bean dark roasted.
A single shot of Espresso is about an ounce and a half of coffee. Espresso is served in a small http://premier-pharmacy.com/product-category/pain-relief/ tiny cup. A 2.5 ounce serving is called a double shot. Milk or cream is never poured into espresso otherwise it is no longer an Espresso drink.
Cappuccino and Latte are drinks made with espresso and milk. In cappuccino, the milk is “frothed” (using the steam wand of an espresso machine) into a “microfoam” approximately about twice the volume of the original milk. In latte, the milk is only “steamed”. For frothing, the milk is converted to a “microfoam”. The microfoam is then poured over the espresso. If the espresso is poured into the microfoam, then the beverage is a “latte macchiato”. In other words, the various types of coffee served at cafes are merely coffee prepared in different way with or without milk. Sugar is added appropriately in the beverage to enhance the taste.
